Science behind the scores
Our methods are documented and open. We do the hard work of turning health and climate research into numbers a kitchen can actually cook with.
Health Alignment Score
The Health Alignment Score (HAS) condenses decades of nutrition research into a single 0–100 number per meal. We built it with PAN International to measure how closely a dish follows what the evidence says we should eat.
Plant Richness
Vegetables, legumes, whole grains, nuts & seeds
Nutrient Density
Protein and fibre relative to energy
Moderation
Sodium, saturated fat and free sugars
Protein Source
Quality and type of the dominant protein source
HAS
0–100
Built on established nutrition science

Explore the methodology →Climate impact
We measure climate impact using Eaternity’s methodology and the Daily Food Unit (DFU). Rather than comparing food by weight, the DFU weighs impact against what a food actually gives you nutritionally — so a portion of lentils and a portion of beef finally become comparable.
Weight alone tells you nothing about what a food delivers.
Daily Food Unit — DFU
CO₂e / DFU
One comparable climate signal per meal.
Based on Eaternity’s Daily Food Unit methodology

Before HAS and the DFU, FOOD2050 scored meals with the Climate Impact Model (CIM) and the Health Impact Model (HIM). Both are still documented in full on our archived methodology page.

We build and check our models together with universities, research institutes and food-sustainability coalitions in Switzerland and across Europe.
Ask us anything — data sources, formulas, validation studies. We'll show you exactly where every number comes from.
